2 US National Grid Introduction to the US National Grid –Why do we need to use the US National Grid? –How is it similar/differ from other systems? –How to read USNG coordinates Tools for Responders Tools for GIS Support Staff

3 Introduction to the USNG  Why do we need to use the US National Grid?  How is it similar/differ from other systems?  How to read USNG coordinates

4 US National Grid Lessons learned have taught us that standardized grids are needed for positional reporting. As far back as Hurricane Andrew, problems were recognized for emergency managers...

5 Florida Adopts the USNG USNG was adopted by the FFCA FDEM adopted the USNG in the States CEMP Florida Fire College, Florida Fire Chiefs Association, FL National Guard developed curriculum and instructor manuals Modules incorporated into Firefighter II curriculum

6 FEMA Adopts the USNG Near term priority approved by Administrator Fugate Establish a standard for FEMA operational maps using the National Grid

7 Introduction to the USNG  Why do we need to use the US National Grid?  How is it similar/differ from other systems?  How to read USNG coordinates

8 What’s wrong with current systems? We already have… – Latitude/Longitude – Township/Range/Section – Street Address and Zip – “Bingo” Grids

9 Latitude/Longitude Multiple formats are confusing DD , DM , DMS 85 59’24.545”W, 30 16’20.063”N All the same location!!!

10 How far is a second anyway? What is the distance from… ’24.545”W, 30 16’20.063”N To here… ’26.292”W, 30 16’14.546”N

11 Township/Range/Section Township/Range/Section grid from the Public Lands Survey System is an important and good system… – basis of land ownership records – been in use for over 180 years

12 Township/Range/Section But a perfect section really doesn’t exist irregular in coastal areas too large to meet needs of ground crews

13 Street Address and Zip Problematic due to… – rural routes – post office boxes – House numbers missing or obscured

14 What do you do when the SIGNS are gone?

15 What do you do when the ROADS are gone?

19 Introduction to the USNG  Why do we need to use the US National Grid?  How is it similar/differ from other systems?  How to read USNG coordinates

20 Developed by the United States Army Corps of Engineers in the 1940s A position on the Earth is referenced in the UTM system by the UTM zone, and the easting and northing coordinate pair. Abbreviated as “UTM” 16R Universal Transverse Mercator

21 is the geocoordinate standard used by North Atlantic Treaty Organization (NATO) for locating points on the earth. is derived from the UTM grid system, but uses a different labeling convention. Abbreviated as “MGRS” 16R GU Military Grid Reference System

22 Practically identical to MGRS. Difference is the datum – MGRS uses WGS84, which USNG uses NAD 83 Coordinates reported identical. Abbreviated as “USNG” 16R GU United States National Grid

23 USNG it has the advantage of being easily plotted on USGS topographic maps by using a simple "right and then up" method instead of having to plot from right to left when using latitude and longitude in the Western Hemisphere. The coordinates are also easily translated to distance since they are in meters. Thus the distance between two coordinates can quickly be determined in the field.

25 Introduction to the USNG  Why do we need to use the US National Grid?  How is it similar/differ from other systems?  How to read USNG coordinates

26 16R GU How to read USNG 100,000 Meter Grid – identification for regional areas Grid Coordinates – Easting and Northing position Grid Zone Designation – for a world-wide unique address, identifies the longitude zone number and the latitude band letter

27 16R GU R17R Truncate for locality just like you don’t have to dial an area code to make a local call… all Florida locations will be 16R or 17R

28 16R GU R17R Truncate for locality 100,000 meter zone designation may be dropped when working locally

29 Truncate for less precision… Locates within 1000 meters Locates within 10 meters Locates within 100 meters Locates within 1 meter 16R GU

30 USNG Easily scaleable Pin-point and cell based locational reporting “Grid within a Grid”

31 Tools for Responders GPS GeoPDF Mapping applications and websites

32 Support for USNG –tools and instructions for GIS staff FDEM’s GATOR –new mapping website with USNG tools FDEP’s Incident Mapper –simple Google Maps mashup with USNG tools GeoPDF’s –new PDF formats have GIS capabilities, including USNG support

33 Global Positioning Systems I have GPS……..why do I need to care about any of this? – USNG can be used with GPS – GPS supplements USNG – USNG will work when your GPS won’t

34 USNG and GPS Most GPS units explicitly support USNG as an option for units If you choose USNG, you must also choose NAD 83 as your datum (or technically, you haven’t chosen USNG) You may also choose MGRS with NAD 83 to be the functional equivalent of USNG

49 USNG in ArcGIS 9.1 USNG National Grid Tools Repackaging of… –Military Analyst –Product line tool set (PLTS) USNG Locational Toolbar Available from ArcScripts –Less complicated, easier to use

50 USNG in ArcGIS 9.2/9.3 Integrated… – Go to X,Y Tool – Identify –Graticules

51 Military Analyst in ArcGIS 9.2/9.3 USNG coordinates may easily be added to a feature class. NAR-C is proper NAD 83 choice - “North American Reference CONUS”
